[XB-49]

I don't think that megapack gives you an air.ini as it doesn't give you any new planes. :wink: Download and install Unified Installer (The link is inoperative). Remember to follow the installation instructions VERY CAREFULLY! However, I suggest that you don't install UI directly into your IL2 game folder. Install it into another folder and paste its contents into your IL2 gmae folder. When prompted to overwrite say yes to all.

Hope it helps,
